A friend of mine has a lathe w/3 phase motor. The original motor control has been changed/replaced so there is only forward. No reverse.
He runs it off a rotary phase converter which does not have any start capacitor/s on it
To start the rpc he hits the switch and kicks a T bar on the shaft with his foot to get it turning. Then all works good.
Somewhere in the back of my head I remember reading that if he kicked the t bar the opposite way so the rpc was turning in reverse it would reverse the lathe motor as well.
Is this true?
Before I give him some quack advice I would like to verify that it is correct.
A guy doesn't need to reverse a lathe too often so this would give him that capability without any rewiring.
What do you elec gurus say?
